RICHMOND, Va. -- A Midlothian family is one step closer to closure following the death of their 27-year-old son, Jacob Baldwin.
Richmond Police say on Saturday, October 12 at 2:14 a.m., officers were called to the 2800 block of West Marshall Street for a report of an aggravated assault.
Baldwin was found near the intersection of West Marshall and North Sheppard near Bingo Beer Co., unresponsive with an injury to his head. He was transported to a nearby hospital and died Wednesday as a result of his injuries.
Baldwin's family spoke at a vigil Friday morning, urging those with information to come forward.

One day later, 27-year-old Nico Rivera of Mechanicsville turned himself in at Richmond Police Headquarters.
According to court records, Rivera was charged with assault and battery in 2020. His case was dismissed.
Saturday, RPD also shared photos of three other individuals they believed had knowledge of the incident, one adult male and two adult females. Monday, police confirmed they had identified and had been in contact with the individuals.
RPD told CBS 6 the individuals were not being considered suspects but were rather being sought for their possible information on the case.
Rivera has since been charged with second-degree murder and will have a bond hearing Tuesday morning at John Marshall Court in Richmond at 9 a.m.
"When there's a violent offense like this, there's inherently a sort of risk to the public, seen by the court usually, so it could be tougher to get out on bond when you have a violent offense. But if you don't have a lengthy record, and there's some assurance he's going to show up in court, then he might very well get a bond," said CBS 6 Legal Analyst Todd Stone.
It's still unclear what led up to the assault, or if Rivera and Baldwin were known to each other.
Stone said details will come from surveillance video and witness testimony, possibly from the people police were searching for.
"If there's people out there who observed it, and then they're interviewed by police, and then they can come testify at trial, if they're testifying to things that amount to a second-degree murder," Stone said. "And that means a malicious assault of another person that results in a death. It has to be malicious and intentional."
Stone says Virginia law says it's not illegal to witness an assault like this and not report it.
However, anyone possibly aiding and abetting in the crime, like handing someone a weapon to be used in the assault, could face the same second-degree murder charge.
